Corner Stability and Rigidity for Square Profile

This structural, two-way connector is designed for forming a fixed 90-degree angle specifically with square tubes and box section. It is manufactured from Thermoplastic Polyester significantly enriched with glass fibre. This superior material composition provides the inherent stability and rigidity for robust square frames:

• Fixed 90° Geometry: Engineered to secure the exact straight corner required.
• Anti-Rotational Grip: The shape is precisely tailored to the square profile, effectively locking the tube in place and eliminating rotation or wobble in the completed assembly.
• Durable: Excellent resistance to heat and a broad spectrum of chemicals ensures prolonged, resilient performance across diverse settings, from demanding industrial environments to commercial fixtures and exposed outdoor installations.

The joint features an appealing, subtly frosted exterior, ensuring a good fitment. This results in clean lines suitable for both moderate heavy-duty functional frameworks and aesthetically prominent retail or decorative displays
